Quick way to transfer degrees from Fahrenheit to Celsius and back
Swedish Anders Celsius and German Gabriel Fahrenheit made history by creating the two most popular temperature measurement scales. The former has found application in the International System of Units, and the latter is now used only by residents of the United States and the Bahamas. At the same time, millions of people around the world are forced to regularly transfer from Celsius to Fahrenheit and vice versa. How to facilitate this process, we will tell in our article.
Connoisseurs of ancient weight measures remember that 20 kilograms is 44 pounds. And runners learned in practice that the distance of 3 miles is about 5 kilometers. But the Fahrenheit temperature remains a mystery to most Europeans. Therefore, arriving in the United States and seeing that there is +50, many fall into a stupor.
Not only have scales of degrees of different sizes, but also different reference points. Zero Celsius is the moment when snow can be replaced by rain at any time. And zero Fahrenheit (-18 ̊C) is a frosty day in the middle of winter, when a good owner and dog will not let out.
Because of this, temperature conversion is a rather complex process and occurs in two stages. To convert degrees Fahrenheit to degrees Celsius, you need to subtract from the temperature of 30 and divide the result by 2. But this will be an approximate value, since the exact coefficients are 32 and 2.2.
But there is a simpler and more witty way to navigate the temperature in Fahrenheit. All you have to do is memorize 4 magic numbers.
As you have noticed, for these values, the numbers are mirrored: 16 becomes 61 and 28 becomes 82. Now, if you're told it's 70 degrees Fahrenheit, you know it's more than 61 (16 degrees C), but luckily less than 82 (28 degrees C). So you can do without air conditioning.
And a funny fact in case you're going to visit Alaska: -40 equals -40 on both scales. However, those who found our life hack too difficult, can always perform a conversion on their phone or even use a special application.
At first glance, percentage problems seem to be extremely simple. But when you need to quickly estimate in your mind the size of the discount on a particular product, we somehow and then fall into a stupor. How to calculate percentages on a calculator and how to do it in your mind with a small mathematical life hack? The answers are waiting for you in our article.

- 04 And that's a degree Celsius. 40. degrees Fahrenheit (cold)
- 16 degrees Celsius is 61 61 Fahrenheit degree (cool)
- 28. degrees Celsius is 82 degrees Fahrenheit (heat)
- 40. Celsius is 104 degrees Fahrenheit (heat!)

This year I decided to get rid of roses and peonies, growing only butterflies, the best flower for flower beds.
